GLASS-HOLDER FOR METAL SASH.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed February 25, 1911. Serial No. 610,874.

To all whom it may concern:

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States,and a resident of New Castle, in the county of Lawrence and State ofPennsylvania, have invented certain new and useful Improvements inGlass-Holders for Metal Sash, of which the following is a specification.

This invention relates to sash or frames for use in buildingconstruction and which are intended to contain glass or other fillingpanels in the spaces provided by the frame; and particularly to thosesash or frames,

which are constructed of metal having a base or flange member, whichsupports the glass or panel and a web perpendicular thereto, whichprovides the lateral limits of the panel opening.

The object of the invention is to rovide a cheap, but efficient andeasily .applled and removable securing means for the glass or otherfilling panel, used in connection with the frame openings, whichsecuring means may be relied on alone to secure the panel or plate ofglass or other material, or may be used in conjunction with a plasticcorner filling such as putty, without interfering with the continuityand adhesion of the latter.

The desired ends are attained, according to the present invention, byforming a depression or seat in the web of the metal structure whichsupports the plate and providing a clip constructed with a back leafadapted to lie parallel with the web of the support, approximately inthe plane of the edge of the plate secured and having a pawl whichenters the seat to resist displacement of said back leaf, and also apresser foot or presser feet projecting outwardly from the back leaf inposition to bear against the plate to be secured and by the resistanceof said plate, to hold the back leaf against the web of the frame; saidback leaf also having a retaining tongue extending in the plane of theback leaf to enter behind the edge of the plate to be secured andprevent displacement of the clip in the plane of the plate. Such adevice is broadly claimed in my co-pending application Serial No.639,830, filed July 521, 1911; said claims being based upon a cured.

disclosure in which the back leaf which carr1es the presser foot orfeet, as well as the retalmng tongue, is provided with a face thatengages a face on the web of the metal structure to revent displacementof the baclc leaf in tie plane of said web; one embodlment disclosingthe additional feature of having the engaging face upon the web,elongated and arranged at such angles that by sliding the clip edgewisealong the web, it is caused to bind upon the plate to be se- The claimsin the present case; are restricted to embodiments in which theinter-enga ing faces on the clip and web are provide respectively, by aresilient pawl carried by the clip and a depression formed in the web;also an embodiment in which there is an additional leaf paralleling theback leaf in position to lie against'the opposite side of the web, saidleaves being connected by a partoverlying the upper face of the web, andthe presser feet being referably duplicated on opposite sides 0 theretaining tongue, the parts being so pro ortioned t at the resilientpresser feet are eft under tension when the clip is pressed down wardsufficiently to permit seating of the locking pawl and the latter beingpreferably carried by that leaf which, when the clip is in use, lies onthe o posite side of the frame web from the leaf which carries presserfeet and the confining tongue.

The invention will be fully understood upon reference to theaccompanying drawing, in which,

Figure 1 re resents a frame or sash, constructed of T-lron in accordancewith U. S. Letters Patent No. 971,011, granted September 20, 1910, andto which my present invention is shown applied by way of illustration.Figs. 2 and 3 are detail perspective views showing opposite sides of theclip in position. Fig. 4 is a sectional view through the metal frame,the glass plate or panel to be secured and the securing clip, thesection being taken in a plane extending through the locking pawl. Figs.5 and 6 are, respectively, a sectional view and front elevation of amodified structure of clip.

1 represents a frame having a base or flange 1, which provides a rest orsupport for a glass plate or panel 2, and a web 1 perpendicular thereto,which, in addition to its other obvious pur oses, in connection with thestructure of t e frame, provides a lateral confining wall for the plateor panel.

For the purpose of holding the plate 2 down upon the base 1, I provide aclip 3, constructed with a back leaf 4, adapted to lie against orparallel with the web 1 of theframe and secured against displacement inthe plane of said web, by a'pawl engaging a seat in one face of theweb,as for instance, the pawl 7 carried by the leaf 5 lyin on the other sideof the web from the lea 4, but joined thereto by apart 6, which overliesthe narrow face of the web; said leaf 1 being also provided with one ormore presser feet 8 (preferably two in number) formed by bending aportion or portions of the clip metal outward so that the feet pro ectfrom the plane of the back leaf in position to bear downward upon theplate 2 to be secured and by their resiliency to exert. considerablepressure on said plate; also a tongue 9, preferably intermediate of twopresser feet 8, extending in the plane of the back leaf, down behind theedge of the plate so as to confine the clip against displacement in theplane of the plate. With the described arrangement, resistance to thepresser feet is exerted in a direction to hold the back leaf against theweb, as well as to hold the pawl 7 in its seat in those forms in whichthe pawl is carriedby the back leaf.

To adapt the frame to receive clips constructed as above described, theweb 1 is provided with a seat or depression 10, preferably having itstop wall perpendicular to the plane of the web so as to afford aneffective stop and in position to permit the pawl 7 of the clip to snapinto it when the clip is pressed down firmly upon the web, and thepresser feet have been brought under tension against the plate. The seat10 is preferably pressed but partway through the web and preferablylocated only at points where it is desired to locate the clips in use.And when so-constructed and lo cated it is preferably given a dimensionlengthwise of the web, which is considerably wider than the pawl, whichis to enter it in order to facilitate putting the clip into positionwithout the delay incident to accurate placing. It is obvious, however,that the purpose would be equally served if the seat 10 were continuousalong the face of the web of the frame as for instance, if it wererolled therein.

To remove the clip for the purpose of replacing a broken plate or panel,it is simply necessary to withdraw the pawl 7 from the seat 10, whichmay be done by forcing a thin instrument up beneath the leaf 5 or byhaving the pawl 7 perforated so as to receive a withdrawing tool. Or theseat 10 might be tapered at its ends, from the full depth of the seatoutwardly to the plane of the web face, so that by forcing the clip 3longitudinally on the web, the tongue would be gradually forced outwardfrom its seat and the clip could be lifted upwardly. Or the leaf 5carrying the pawl 7 may be forcibly drawn outward without care ofpreserving the clip and the clip replaced by a new one in putting in anew plate or panel. The cheapness of the construction permits of this ifdesired.

It will be observed from the disclosure of the drawing that not onlywill the clip not interpose obstruction to the application of theordinary putty or other plastic packing in the angle between the plateand the web, but keying space is afforded both by the lower edge of theleaf 5 and the spaces beneath the presser feet 8.

In the arrangement shown in Figs. 5 and 6, the retaining clip is notdesigned to straddle the web 1 but on the other hand lies against andengages with only one and the same side of the web. This modified formof clip consists of a leaf 4? having a pawl or tongue 4 similar to andhaving the same function as the pawl 7 in the other structure. The leaf4 extends for its full width to thebase or flange l, and is thencefolded upon itself as indicated at 5, and extended upwardly to aposition well above the plate or panel 2. The said folded portions 5 arelocated intermediate the edge of the plate 2 and the web 4 andcooperating with the tongue t", said part 5 affords a secure fasteningfor the clip. The upwardly disposed part of the member 5 is bentoutwardly and downwardly to provide a presser foot 5 for retaining thepanel against the base 1*.

I claim v 1. A clip for frames having a plate supporting base and a webat an angle to said base; said clip comprising a web-abutting memberhaving struck therefrom a tongue transversely resilient butlongitudinally rigid relatively to said member; said webabutting memberalso carrying a tongue extending in the plane thereof adapted to engagethe edge of a plate supported on the base of the frame, and with apresser foot extending at an angle to said tongue and resilient in thedirection of the tongue.

2. A clip for frames having a plate supporting base and a web at anangle to said base; said clip comprising a web-abutting member havingstruck therefrom a tongue transversely resilient but longitudinallyrigid relatively to said member; said webabutting member also carrying atongue extending in the plane thereof adapted to engage the edge of aplate supported on the base of the frame, and with a presser footextending at an angle to said tongue and resilient in the direction ofthe tongue; said web-abutting member comprising two opposing leavesadapted to embrace the web, one o s engaging tongue, and the othercarrying the presser foot and the plate-engaging tongue.
